Autofloat Switches
•
The automatic bilge pumps use float (autofloat)
switches to automatically turn On the pumps when-
ever water rises to a preset level in the bilge.
•
The autofloat switches are normally mounted next to
the bilge pumps they control.
•
The autofloat switches should be tested often for
proper operation as follows.
To test a float switch:
1. Turn On the float switch by twisting the white plas-
tic knob 1/4 turn.
2. The bilge pump should turn On.
3. If twisting the knob does not turn the pump on,
check the circuit breaker on the battery manage-
ment panel.
4. If the circuit breaker is on, but the pump still does
not work, it may indicate a bad switch or possibly a
low battery.
5. Release the knob to lower the float and return the float switch to auto mode.
